Solar Globe

Used to geometrically measure the latitude and longitude positions of spots on the Sun´s surface. DeLury´s globe was used to make direct measurement of sunspots´ positions using images projected onto the globe. Programmable calculators were thirty-five years in the future! The four solar images were taken over several days in August 1930. Note the dark sunspot moving right to left due to the Sun´s rotation. Canada Science and Technology Museum
